Portable medical cold compress device

Abstract

The invention relates to a portable medical cold compress device which comprises a host and a cold compress bag, wherein a water circulating module, a refrigerating module and a detection control module are arranged in the host; the water circulating module comprises a water tank, a heat exchanger, an impeller pump, a three-way reversing valve and a two-way valve; the refrigerating module mainly comprises a micro compressor, a condenser, a throttle valve, an evaporator and a fan; the detection control module mainly comprises a temperature sensor, a pressure sensor, a power supply and a control circuit on the basis of ATmega32; the detection control module detects the temperature and the pressure inside a liquid circuit of the water circulating module, compares the detected temperature and pressure with set cold compress temperature and pressure, enables the water circulating module to operate in different modes and controls the refrigerating module to be started or shut down. The portable medical cold compress device is rapid to refrigerate, is controllable in the cold compress temperature, time and pressure, can implement multi-parameter regulation and is suitable for treatment in hospitals and outdoor on-site rescue.

Description

technical field [0001] The invention belongs to a portable medical cold compress that can realize multi-parameter adjustment, in particular to a portable medical cold compress that has the functions of setting and adjusting cold compress temperature, cold compress time, and cold compress pressure. Background technique [0002] Bruises and sprains are common accidental injuries in sports, and the affected limbs may experience varying degrees of swelling and pain. If the cold compress can be used in time after the injury, it can relieve pain, stop bleeding, cool down, and reduce inflammation, which is very important for shortening the recovery time. At present, ice packs, evaporative refrigerants, and cold wet towels are commonly used for cold compresses. These methods may cause frostbite and cause secondary damage, and there are problems such as short cold compress time, insufficient contact between the cold compress medium and the affected area, and limited use occasions.
